Specification of'Letters Patent.

Patented Nov. 26, 1912.

Original application filed March 27, 1912, Serial No. 686,575. Divided and this application filed July 6,

1912. Serial No. 707,976.

' Writing Machines, of which the following is a speci cation.

My presentinvention relates to tabulator stops and devices for retaining said stops on a stop support and the principal objects of the invention are to provide improved 'tabulator stops and improved retaining devices of the character specified.

To theabove and other ends my invention consists in the features of construction,

combinations of devices and arrangements ofparts hereinafter described and particularly pointed out inthe claims.

The present application is a division of my prior Patent, No. 1,037,076, granted- August 27, 1912.

In the accompanying drawings, Figure 1 is'a fragmentary side elevation, partly in section, of a Monarch typewriting machine embodying my invention, parts of the machine being omitted and parts broken away. Fig. 2 is a fragmentary vertical sectional view taken on a plane indicatedby the dotted. line in in Fig. 1 and looking in the direction of the arrow at said line. Fig. 3 is a vertical sectional view taken on a lane indicated by the dotted line y-y in ig. 2 and lookingin the direction of the arrows at said line. Fig. 4 is a perspective view of a tabulator stop. a

As shown in Fig. l, the main frame com prises a base 1, posts 2 and a top plate 3, s4 to which are secured fixed track-ways 5 and 6 cooperating through anti-friction balls 7 with the rear bar 8 of a platen carrier or carriage which further includes forwardly extending end bars 9. Said end bars provide bearings for the axle 10 ofarotary platen 11, with the front faeeof which coiiperateprinting instrumentalities of the usual description. The carriage is urged leftward by a spring drum 12 which is connected by a strap 13 with an arm 14 depending from the carriage.- The end bars 9 pivotally support the arms 15 of a; feed rack 16 which normally meshes with a feed pinion 17 securedto a shaft 18 bearing in a'bracket 19 on the top plate. Operatively connected to the shaft 18 is an escapement wheel with which cotiperate the usual escapement dogs that are pivotally supported on .a bracket 20 depending from the lop plate, said wheel and dogs being omitted from the drawings.

Tabulating mechanism is shown herein comprising a set of upright denominational stop levers 21 pivoted at 22 in a frame 23 detachably secured to the main frame. The upper portions of the levers '21 are curved forward, terminating in denominational stops proper 24, these stops being adapted. to be actuated by the usual key controlled devices and thereby projected forward to cooperate with the novel column stops hereinafter described. The actuation of the stop levers 21 operates carriage releasing devices,

not shown herein but disclosed in the parent application aforesaid.

Projecting rearward from the slide bar 8 column stop bar, 40 toothed at its front and rear faces, the notches 41 between the teeth being a letter space distance apart. The stop bar 40 is of ordinary construction butis provided with novel stop retaining or lockmg devices :for the column or tabulator stops which said step bar 40 is, adapted to receive. To accommodate these retaining devices the front face of the bar 40 is formed with a longitudinal groove-42. Said groove receives a rod 43 circular in cross section, which is constantly pressed forward by springs 44 seated in depressions 45 in the rod, there being preferably three of these springs, two near the ends and one midway between. Said springs tend to force the rod 43 out of its seat 42 but this is revented by screws 46 one near each end 0 the rod, and further by a central restrainingfinger 47. Said finger registers with the upper portion of one of the teeth at the front of the stop bar 40, the lower portion of said tooth below the r0d'43' being cut away to accommodate the finger 47 which is so narrow that it'does not encroach on the neighboring. notches and so prevent the adjustment of sto therein. The finger 47 is part of an anguar bracket 48, the body portion of which extends ben'eaththestop bar and is secured thereto by a screw 49.

i A rectangular column stop magaz ne or containerfi t islprovided, said container havare arms 39 which provide a support for a ceives a'spring plunger 67 having a conredouter end.

Housed in the magazine 54 is a set or series of' column'stops 70. Each column stop may be described generally as a rectangular plate of such size as to tit loosely within the' container 5 1, the internal cross dimensions of which are slightly greater than the corresponding dimensions of the'stop. Each stop is formed with a notch 71 which enables it to tit over and rest on the supporting rod 6 1, The forward edge of each notch 71 is provided. with a slight depression 72 to cooperate with the retaining or looking rod 43' when the stop is ejected on to the stop bar- 4 0. The upper edge of each stop is beveled Y or inclined from right to left, as indicated at while the lower edge is pointed or formed with a double bevel 70". The bevel 70 f-acilitates the reentrance of the step into the magazine. enabling it to earn back such stops as may be within the magazine at the time, and also to cooperate with the pointed or beveled end of-the plunger 67 to force The said plunger backward in'its scat.

pointed bevel 70 at the bottom'of each stop facilitates its cooperation with the notches 41 in the stop bar 40 during stop setting At the top, each stop is formed operations. with a notch or recess 7 3' to cooperate with an ejector hereinafter described. The magazine may be adapted to receive any desired number of column or tabulator stops, that illustrated. herein accommodating some twenty-fivestops. These stops are strung together face to face on the rod 64 and. are forced along the same toward the left by a spring pressed follower. not shown herein but fully. disclosed in my parent.- application aforesaid. The left-hand end of the magamine 54 is closed by a guide member or head i 77 between-which and the floor plate 56 is an opening or mouth through which the column stops pass out: of and into the magazine.

The steps are ejected from the magazine by devices comprising a slide 85 provided with a central'rib 86 which is guided in a vertical groove or slot 79 in the .head 77. Forward of the slide 85 is a. retracting slide 89 which is also vertically guided in 'the head 87. Normally the ejector 85 is maintained so that its bottom face is above the underlying column stop in the magazine, but when the slide is pushed down its rib 86 will engage in the notch 73 of the outermost column stop a'nd'will. force said column stop vertically downward out of themagazine through the mouth therein and on to the stop bar 40, the notch 71 enabling the stop to straddle the. stop her and fit into the appropriate notches 41 therein. The fit of the rib 86 in the notch 73 is comparatively close and the parts will cooperate to guide the downwardly moving stop in. a straight course and to prevent wobbling of said stop. During its passage downward over the'stop force theretaining rod 43 slightly rearward against its spring, but as soon as the depression 72 comes opposite said rod the rod will bar the forward edge of the notch 71 will slide outward again and engage with said depression to lock or retain the stop on the stop bar 40, asshown m Fig. 3. The retaining or locking devices are'quite efficient .in operation but owing to the fact that the surface of the rod 13 is rounded as is also the edge of the depression 72, said devices will. readily engage and disengage with a minimum of friction, increasing the facility with which thelocking and unlocking, is accomplished, and lessening the'liability of sticking which frequently occurs in locking devices having straight or angularly disposed faces.

The operation above described may, be repeated until the desired number of column steps have been properly set in position on 4 the column stop bar. The rear lower corner of each column stop 1s cut away, as indicated at 70, so that the column stops when set on the stop bar may clear the eseapement wheel (not shown). r

The slide or retractor 89 terminates at its lower end in a toepiece or lug 91 which un{ (lei-lies,- portions of the set column stops when 'said stops are brought into register withthe part .91. The retractor 89 is adapt ed to he slid up or lifted from normal position in order to cooperate with the set column stops and force them upward back into the magazine, thus clearing the column stop bar.

The ejector or stop setter 85 is operated by key controlled devices comprising a link 94 which 'conn ectssaid ejector with a crank arm 96 on a rock shaft. 97 hearing at its right-hand end in an ear 100 of a bracket 101 secured by screws -102 to the bracket '20. The left-hand of the rock shaft bears in a stationary bracket (not shown). Secured to the rock shaft 97 near it'spleft 'end'is a crank arm 105 to which is pivotally connected a push rod 109 provided with a stopsetting key 110. A restoring spring 111 is connected to said crank arm 105. The retractor 89 is actuated to clear the sto bar .of stops by devices comprising a lln with a clearing key 12 1.v Arestoring... a

spring 125 is connected to the crank arm 121.

Aside from the column stops and the associate locking devices therefor that are on the latter being notched and one of the legs being formed with a recess; that the notch, in the present instance 73, is rectangular; that the, recess 72 is rounded; that by notch,- ing or cutting out the tabulator stop as at 71-,

-a bifurcated tabular stop is provided one fork of which is recessed and the top side of which is notched; that said notch is centrally arranged; that the fork aforesaid'is recessed on its inner edge while the other fork of the bifurcated stop is provided with a cutaway; that acolumn stop bar isprovided which has a longitudinal recess; that a spring premed locking member is supported within the recess; that in the present instance saidlocking member is a cylindrical bar extending lengthwise of the slot formed in the front side of the column stop bar; that the column stop bar is adapted to receive a plurality of column stops from a stop magazine, said column stop being 'provided with a centrally arranged notch; and that an ejecting device'is provided which registers with the column stops as they are successively brought into position to be ejected.

It will further be understood that the novel stops herein described may be usedin connection with stop setting and retracting 40.

devices different in character from those shown; also that parts of the invention may features of the invention may be adapted for use inother connections than with key set tabulatin'g mechainsm; and that various detailed changes may be made without departing from the spirit and scope of said invention. r
